In short
- Glucose shows your sugar right now, HbA1c the average of the last ~3 months.
- The “prediabetes” range is a warning — it can often be reversed.
- Target: fasting glucose below 5.6 mmol/L, HbA1c below 5.7%.
- You calm it with less sugar, more fibre, a walk after meals and exercise.
- Glucose of 7.0 or more, or HbA1c of 6.5% or more, belongs with a doctor.
Blood sugar is one of the most important markers of metabolic health. The good news: this is where lifestyle has enormous power. Values can often be calmed before they become a problem.
Glucose and HbA1c — what is the difference
Fasting glucose shows what your sugar is at a given moment. HbA1c (glycated haemoglobin) tells you the average of roughly the last three months. That makes it excellent for following a trend. Together they give a reliable picture.
What your values mean
| Status | Fasting glucose | HbA1c |
|---|---|---|
| Optimal | below 5.6 mmol/L | below 5.7% |
| Prediabetes | 5.6–6.9 mmol/L | 5.7–6.4% |
| Diabetes (likely) | 7.0 or more | 6.5% or more |

How to calm blood sugar naturally
1) Fewer refined carbohydrates and sugary drinks
Sugary drinks and white-flour products raise sugar the fastest. Swap them for water and whole-grain sources.
2) Fibre every day (≥30 g)
Vegetables, legumes and whole grains slow the rise in sugar and improve insulin sensitivity.
3) The order of your meal
Eat fibre and protein first, and starch only afterwards. This flattens the sugar spike after the meal — a simple but effective trick.
4) A walk after meals
Even 10–15 minutes of walking after eating noticeably lowers post-meal sugar. Muscles “use up” glucose.
5) Exercise and sleep
A combination of endurance exercise and strength training improves glucose control. Poor sleep makes it worse.
A realistic goal: because HbA1c reflects three months, a change shows up after about 12 weeks of consistent habits. A follow-up report confirms your progress.

Upload your report and we explain your glucose and HbA1c in plain language. We prepare a concrete plan to calm your blood sugar and track your progress over time, so you can see it working. Related: cholesterol, LDL and ApoB, which often go hand in hand with blood sugar.
Frequently asked questions
What does prediabetes mean?
Fasting glucose of 5.6–6.9 mmol/L or HbA1c of 5.7–6.4% means the prediabetes range — a warning that can often be reversed with lifestyle.
What is the difference between glucose and HbA1c?
Glucose shows your current sugar level, HbA1c the average of roughly the last three months.
How fast can I lower HbA1c?
Because HbA1c reflects three months, a change shows up after about 12 weeks of consistent habits.
